Lock Box Labs PGP Tools comprise two command line tools and associated ant tasks for manipulating Open PGP key rings and performing encryption, signing, key generation, and certification operations. The toolkit is fully written in Java and the lbpg-tools jar provided with the distribution and the source code will work with JDK 1.4 or later. The toolkit is built on the Bouncy Castle APIs.
Arandomd is a network daemon that provides statistically tested output from a single ARC4 stream cipher generator to anyone able to connect to its listening TCP port. As multiple consumers cause it to reseed itself from a separate, strong random source, it is expected to produce consistently unpredictable results for cryptographic purposes. A configurable number of tests from the Statistical Test Suite for Random and Pseudorandom Number Generators must be passed before output data is sent to the client. It may be be useful in low-entropy environments, such as compute clouds, for generating high quality key material for strong cryptography.
sphlib provides optimized implementations in both C and Java of cryptographic hash functions. The C code includes "small footprint" variants optimized for architectures with low L1 cache (e.g. WiFi routers running OpenWRT). The C code comes with a command-line tool that can serve as a drop-in replacement for md5sum, sha1sum, sha256sum, etc. for all implemented hash functions. The Java code is compatible with J2ME. There are implementations of fourteen "second-round" SHA-3 candidates, for all output lengths: BLAKE, Blue Midnight Wish, CubeHash, ECHO, Fugue, Grøstl, Hamsi, JH, Keccak, Luffa, Shabal, SHAvite-3, SIMD, and Skein. Some pre-SHA-3 hash functions (including MD4, MD5, SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, RIPEMD-160, and others) are also implemented.
Novosec Bouncy Castle Extensions provides some extensions to the Bouncy Castle Cryptography framework. It features an OCSP (RFC 2560) server and client that work with the Bouncy Castle OCSP generators and parsers, and a full tested implementation of CMP (RFC 2510, RFC 2511) generator and parser classes, that also rely on Bouncy Castle classes.
